Background: Impaired fasting glucose (IFG) is a prediabetic condition and is a high-risk state for developing diabetes and associated complications. The aim of this study was to explore the association of vitamin D with insulin secretory function among the IFG subjects. Materials and Methods: This was a prospective cross-sectional study conducted in the Department of Biochemistry and Cell Biology, Bangladesh University of Health Sciences (BUHS), Dhaka, Bangladesh;from June 2016 to May 2017, on forty-six (46) IFG subjects. Serum blood glucose was measured by glucose-oxidase method, Fasting serum lipid profile (Total cholesterol, TG and HDL-c);liver enzyme like alanine aminotransferase (ALT) was measured by enzymatic-colorimetric method;Serum creatinine was measured by colorimetric kinetic method;Serum Insulin and vitamin D [25(OH)D] were measured by ELISA method;insulin secretory capacity (HOMA%B) and insulin sensitivity (HOMA%S) were calculated by Homeostasis Model Assessment (HOMA) using HOMA-CIGMA software. Results: Among 46 IFG subjects, 22 (47.8%) were male and rest 24 (52.2%) were female and their mean age was 40 (±8) years. Mean fasting serum glucose level of the study subjects was 6.33 (±0.23) mmol/l and mean postprandial serum glucose level was 7.23 (±0.41) mmol/l. Mean serum vitamin D level of the study subjects was 26.54 (±8.83) ng/ml. Mean HOMA%S, HOMA%B and HOMA%IR of the total study subjects were 48.34 (±16.70), 102.16 (±23.13) and 2.28 (±0.70) respectively. Insulin secretory capacity (HOMA%B) was significantly higher (p = 0.047) in the subjects having higher vitamin D [25(OH)D level ≥ 20 ng/ml] compared to the subjects having lower vitamin D [25(OH)D levels Conclusion: High prevalence of hypovitaminosis D exists among IFG subjects. Vitamin D is associated with insulin secretory function in IFG subjects. Population based prospective studies using larger sample size should be done to confirm the results.

Nipah virus (NiV) is a highly infectious zoonotic pathogen that poses a significant threat to human and animal health. First identified in Malaysia in 1998, NiV has since caused several outbreaks in Southeast Asia, with sporadic cases reported in Bangladesh and India. The virus is primarily transmitted to humans through direct contact with infected animals, primarily fruit bats, or through the consumption of contaminated fruits and their juices. NiV infection presents a wide spectrum of clinical features, ranging from mild respiratory illness to severe encephalitis, with a high case fatality rate. The incubation period typically ranges from 4 to 14 days, during which patients develop fever, headache, myalgia, and respiratory symptoms such as cough and sore throat. As the disease progresses, neurological signs become prominent, including altered consciousness, seizures, and focal deficits. Severe cases may exhibit acute respiratory distress syndrome and multi organ failure. Laboratory findings often include lymphocytopenia, thrombocytopenia, and elevated liver enzymes. Diagnosis of NiV infection requires specialized laboratory testing, including reverse transcription-polymerase chain reaction (RT-PCR) and serological assays. Currently, no specific antiviral treatment exists for NiV infection, and management primarily focuses on supportive care. Prevention and control strategies encompass public health interventions, surveillance, and raising awareness among healthcare providers and the general population. The emergence and re-emergence of NiV highlight the urgent need for continued research, improved diagnostic capabilities, and the development of effective vaccines and therapeutics to mitigate the impact of this deadly virus.

Showkat kabir Mohammed Moinul Hoque Nirupam Chowdhury Mohammad Shish Rahman Nawreen Binte Anwar Shah-Noor Hassan Department of Community Ophthalmology Bangabandhu Sheikh Mujib Medical University Dhaka Bangladesh Department of Ophthalmology Bangabandhu Sheikh Mujib Medical University Dhaka Bangladesh

Background: Bangladesh’s tea industry is essential to the country’s economic expansion. Since tea workers in Bangladesh are marginalized within our community, they have limited access to comprehensive eye care services. Productivity and well-being are cornerstones of comprehensive health care strategy. Ocular disorders are influenced by life expectancy, sociodemographic status, and the epidemiological transition. In this context, the state of ocular health and the many eye illnesses remain to be significantly addressed. Purpose: To evaluate the pattern of eye diseases among tea workers in a tea estate of Bangladesh. Methods: This cross-sectional observational study was carried out in Halda Valley Tea Estate, Nazirhat, Fatickchari, Chattogram, Bangladesh, under the supervision of the Department of Community Ophthalmology, BSMMU, following ethical clearance and approval by the IRB board of BSMMU. With informed written consent and approval from the authority of the tea estate, a total of 110 tea workers were recruited. Socio-demographic characteristics, ocular findings, and patterns of eye diseases were determined and recorded. Results: The mean age of the study participants was 39.60 ± 11.63 years. The maximum (58.1%) study participants were 31 - 50 years old, female (64.5%), illiterate (82.7%), and tribal (71.8%) indigenes. Eye diseases were found in 94.5% of workers. Presbyopia (28.2%), cataracts (27.3%), and refractive error (26.4%) were the most common. Tea workers with eye diseases were significantly older than those who did not have any eye diseases (40.20 ± 11.57 vs. 29.17 ± 7.31 years, p Conclusion: A significant number of tea workers had eye diseases, of which presbyopia, cataracts, and refractive error were the most common.

Background: Cardio-renal syndrome is the leading cause of death globally. Acute kidney injury (AKI) is a major complication among patients admitted in Coronary Care Unit (CCU) with acute coronary syndrome (ACS). AKI in ACS patients is associated with higher morbidity, mortality and prolong hospital stay. Objective: To determine the incidence, risk factors and short term outcome of acute kidney injury (AKI) among the patients admitted in CCU with ACS. Methods: This cross sectional study was conducted at Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2013 to December 2013. Following selection criteria a total of two hundred (200) patients with ACS were studied. AKI was defined according to the KDIGO guideline and further categorized by RIFLE criteria. Data of patients with AKI and those without AKI were analyzed and compared by statistical tests. Results: Majority of the study patients were male (79.5%). AKI was developed in 40 of the 200 study patients (20.0%). The mean (±SD) age of the study patients was 60.1 ± 11.1 years in patients with AKI and 55.9 ± 10.1 years in patients without AKI. Our data analysis showed that older age (>65 years), diabetes mellitus, dyslipidemia and smoking were significantly correlated to the development of AKI. Mortality was significantly high in AKI group (7.15%) compared to no AKI group (1.25%). Out of 27 patients who achieved renal recovery most (80.8%) belonged to risk class. Severity of AKI showed significant effect on renal recovery and final outcome. Conclusion: This study demonstrated that, incidence of AKI among patients with ACS was 20%. Elderly patients, diabetes mellitus, dyslipidemia, and exposure to smoking were significantly associated with development of AKI in ACS.
